Abstract

The invention provides a readily deployed insulating seal for the hearth opening eliminating airflow to and from the chimney flue that utilizes a safe and uncomplicated expanding Pneumatic filled mass that acts as a closure preventing heat loss from exiting the room and blocking cold air from entering.

Claims

exact text as granted — not AI-modified
What is claimed: 
     
         1 . A device consisting essentially of:
 A fire retardant inflatable product that eliminates energy loss through a fireplace flue;   that prevents drafts from entering the property from the fireplace flue;   that insulates the fireplace flue from airflow into or out from the property;   that is self-anchoring in the fireplace hearth;   that is scalable to accommodate variances in the hearth openings;   that is easily deployed by inflating the device through a pneumatic fill valve (illustrative example of an embodiment of one manifestation of a pneumatic fill valve is displayed as  FIG. 2 );   and is easily deflated for removal and use of the fireplace as intended by the designer.   
     
     
         2 . The device as described in  claim 1  as it relates to an energy management device for fireplace(s). 
     
     
         3 . A design comprising:
 A shaped vessel that essentially creates an anchoring mechanism as part of its basic shape;   that contains an easily accessed pneumatic fill valve that allow for ready access to install or remove the device from the hearth;   that is purposefully produced in multiple sizes to accommodate variances in hearth openings and scalable in deployed size to cover all size parameters between produced sizes;   and creates an insulating barrier between the inside and outside air.   
     
     
         4 . The design as described in  claim 3  as it relates to an energy management device for fireplace(s).
